GuruNanda Teeth Whitening Pen,(0.06 fl oz)-20 Uses, Vegan & Gentle on Teeth Pro Formula - Hydrogen Peroxide Whitening Gel Pen, Cruelty-free, Mint Flavor

I love this product. I was a bit hesitant but actually works well. Didn’t leave my teeth sensitive and definitely whiten them a lot. I find if you aren’t consistent with the product you won’t see a difference though. Over all recommend!!

This makes my teeth whiter and doesn't make my teeth sensitive. It's a great deal and I highly recommend this.

Greta product! Definitely worth the price and it lasts a good amount of time! However if you want this product to really work make sure u purchase the pulling oil too. Love the clean ingredients however this won’t make ur teeth white instantly. You will need to take more care and attention to your teeth for a full effect. Overall I give it a 8.5/10

decent

This really a good teeth whitener

10/10

Purchased as a review from an Instagramer that purchased for $1.25 at Dollar Tree. Now, I was fine with paying double, $2.50 isn't bad (though hey, Amazon, your video in the photos says same price as dollar tree). Anyways, most pens are a minute or less. This pen? You're supposed to smile wide with lips not touching teeth (puckered, essentially) for 15 minutes. Can you do that? I tried. My husband asked what was wrong with me.Then 30 minutes no drinking or eating. Ok, cool. My husband just thinks I'm being weird. Nooo. The weird came from the white spots it left all over my teeth. 🙄 And no, my teeth weren't bad to begin with.I've seen high remarks on this brand's other products, so I may give some of them a go. As for this pen, it's a NO.

Great
